Description

DETAILED DESCRIPTION OF THE INVENTION E-INDUSTRIAL APPLICATION FIELD The present invention relates to an improvement in a method for painting tile with shades of the same color.

[Prior Art] Conventionally, methods for applying shades of the same color in tile painting include a method using screen paint and a method using intaglio pad paint.

A method using the screen paint shown in FIG. 2 will be explained. First, from the original picture (not shown), make 1 block copy by shade of similar color.
, 2, 3.4. Next, each version 1 (2, 3, 4
) to create shading positives 5 (6, 7, 8) for each shading.

Next, create screen plates 9 (10, 11, 12) for each shade from each shade positive 5 (6, 7, 8), and create shades of similar colors corresponding to each screen plate 9 (10, 11, 12). Using paints (not shown), paint in similar colors on the tile base (not shown) to complete the shading work.

Next, although not shown, a method using intaglio pad paint will be described. First, in the same manner as described above, a 'a light positive is created for each similar color. Next, intaglio plates are created for each shade from each shade positive to obtain a plurality of intaglio plates. Next, multi-color painting is applied to the tile base using shading paints of similar colors corresponding to each intaglio, completing the shading painting work of similar colors.

[Problems to be Solved by the Invention] However, the conventional tile painting method in which shading of the same color is applied has the following drawbacks.

(a) Since it is necessary to create a plurality of illustrated plates made of screen plates or intaglios for each similar color, the manufacturing cost of the illustrated plates increases.

[1)] Since it is necessary to produce a wide variety of shading paints of similar colors for each painted plate, the cost of manufacturing the paints increases.

(Since painting work is required for the number of sheets of the C1 illustrated edition,
Work costs increase.

(d) For the reasons described in (a) to (C1) above, the cost of painting the tile base with shades of color becomes extremely high.

Means for Solving Problem E] In view of the above circumstances, the present invention provides a method for solving problems without creating multiple painted plates for each similar color and without using several types of light paints for each similar color. , repeated numerous experiments in order to paint the tile base with shades of the same color. As a result, the IfI inventor discovered that when painting a tile base with a single color paint,
It was discovered that by expressing shading by the size of halftone dots of painted paint, and firing the obtained tile base, a tile with clearly expressed shading of the same color can be obtained, and based on this knowledge, the present invention was completed. reached.

That is, in the present invention, as shown in FIG. 1, a painted plate 30 is created from a plurality of shading positives 25, 26, 27, 28 created for different shadings of the same color, and the shading of the same color is applied to a tile base (not shown). In the method of painting, the plurality of shading positives 25
, 26, 27. This means painting in shades of the same color.

[Function] Since one picture plate 30 is created from the composite positive 29 having light and shade parts, light and shade parts are formed in the picture plate 30, and - light and shade painting of the same color can be made on the tile base by repeated printing. .

[Description of Examples] Hereinafter, the tile painting method according to the present invention will be described based on the order of each step of the example using screen paint shown in FIG.

In the first step, the original painting (not shown) is painted in a similar color (for example, red,
In addition to separating the colors into yellow, blue, black) parts, each similar color part is divided into multiple levels of shading difference, and each similar color is divided into shading parts 21.22, 23.24
(The drawing shows only one color system). Note that if there is only one similar color, the above color separation is omitted.

In the second step, each block 21 (22, 23,
24) and a contact screen (not shown) to create a contrast positive 25 (26, 27, 28). A mock-up of a contact screen! ! (halftone dots or grain, etc.)
The number of meshes and meshes are selected as appropriate for each version, but the number of meshes is generally 40 to 100 (preferably 50
~60) Use a 7 inch wire. When shooting, the brightness of each block 21 (22, 23, 24) is different, so
By appropriately adjusting the exposure time, etc., each shade positive 25 (26, 27, 28) with sharp halftone dots or grains is obtained. When there are a plurality of similar colors, shade positives are created for each similar color.

The third step is to create shades of positive 25, 26, 27.2 of each similar color.
8 to create a composite positive 29. The composite positive 30 may, of course, be one in which the light and dark positives 25, 26, 27, and 28 are superimposed so as not to shift, or may be one in which the superimposed images are photographed as negative and positive. When there are multiple similar colors, a composite positive is created for each similar color.

In the fourth step, an illustrated plate 30 consisting of one screen plate is created from the composite positive 29. As an example of a method for creating the illustrated version 30, the screen 3 stretched on the frame 30a is
A photosensitive agent (not shown) is applied to the photosensitive material 0b, and a composite positive 29 is brought into close contact with the dry surface of the photosensitive agent, followed by printing and development. Next, after washing away the uncured photosensitizer, it is dried to obtain the illustrated plate 30. When there are multiple similar colors, an illustrated plate is created for each similar color.

In the fifth step, the painting plate 30 is used to paint the tile base (not shown) in shading with a single color paint corresponding to the painting plate 30 in multiple printings to complete the painting work.

Note that when there are a plurality of similar colors, the painting work is completed by performing multicolor painting using the painting plates of each similar color.

(Another Example) Next, although not shown in the drawings, an example using an intaglio pad paint will be described. The first step of creating a shade-separated block, the second step of creating a shade positive, and the third step of creating a composite positive are the same as in the embodiment using the screen paint. The difference between this example and the example using screen paint is that in the fourth step, a painted plate for each similar color is created from an intaglio plate, and in the fifth step, a painted plate made of the intaglio plate is created. Use a single color paint that corresponds to the painting plate to paint the tile base in one printing (-times transfer), and when there are multiple similar colors,
The point is to complete the painting work by painting in multiple colors using painting plates of similar colors. An example of a method for creating a painted plate made of intaglio is to apply a photosensitizer to a mirror-finished plate material, bring a synthetic positive into close contact with the dried surface of the photosensitizer, and then
The print is developed. Next, the uncured photosensitizer is washed away, and after drying, the photosensitizer is cured by heating if necessary, and a painted layer made of an intaglio is obtained through a corrosion process.

When there are a plurality of similar colors, an illustrated plate made of intaglio is created for each similar color.

[Effects of the Invention] As detailed above, the tile painting method according to the present invention has the following excellent effects.

■ Since a composite positive is created from the light and dark positives created separately for shading, halftone dots or grains in the composite positive are sharply expressed. As a result, the shading of the same color can be clearly expressed even with a single printing of paint of a single color.

- Since it is only necessary to create one picture plate made of a screen plate or an intaglio plate for each similar color, the manufacturing cost of the picture plate can be reduced.

■ Various colors! Since I-tan can be expressed with a single color of paint, paint manufacturing costs can be reduced compared to the conventional method which requires a wide variety of shading paints.

■ Since gradation painting can be done with one painting layer of each color, the cost of painting work can be reduced compared to the conventional method which uses a plurality of painting plates of each color.

(2) The synergistic effects described in (1) to (2) above can significantly reduce the cost of painting tile bases with shades of light and shade.
